Specification forming part of LettersbPatent No. 116,365, dated June 27,i871.

To all 'whom it may concern:

Beit known that I, GEORGE B. SNnDER, of the city, county, and State ofNew York, have invented certain new and useful Improvements inBase-l3urning Fire-Place Heaters and Stoves, of which the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawing forming part of this specication, in which- Figurel represents a side elevation of a fireplace heater constructed inaccordance with my invention; Fig. 2, a sectional elevation taken asindicated by the line me in Fig. 4; Fig. 3, a plan 0f the heater; Fi g.4, a horizontal section through the line y y in Fig. l; and Fig. 5, alike section through the line z z.

Similar letters of reference indicate corresponding parts throughout theseveral iigures.

My invention consists in a certain arrangement of air-heating orradiating pipes, through which the products of combustion are passed,the saine consisting of upper-side pipes, which connect with the body ofthe heater near its top side dippipes, and up-takepipes that connect bybranches above with the main escape-pipe or iiue. By this arrangement ofthe' pipes that carry oli' the products of combustion, all the availableheat derivable from the latter is utilized in heating the air outside ofthe pipes without interfering with or impair-ing the draught. Theinvention also consists in a novel arrangement of an air-heating chamberor chambers in the case of the heater, into which the air to be heatedis introduced through holes in the bottom, and distributed when warmedthrough holes inrthe top, said air-heating chamber or chambers beingexposed on its or their sides to radiation from the ash-pit and to thebase-liuc of the heater. The invention likewise consists in a novel andconvenient means of hanging and securing the front plat-e of a lireplaceheater, by inserting said plate in rear of side lugs on the base-plate,and securing it by a screw to the top of the heater, whereby increasedfacility is afforded for introducing said front plate in rear of thecenter ornament of the mantle-piece and for holding it in its place.Furthermore, the invention consists in a novel construction ofthefuel-reservoir by making the lower part or throat that, on saidcurtain-like portion being turned, allow of its detachment and removal,and this by a certain arrangement and enlargement of the doors of theheater or stove without disturbing the structure generally. Thisprovides for the ready replacement, by a new throat or portion whenrequired, of that part of the fuel-receptacle in base-burning heatersand stoves which is the soonest destroyed by the action of the lire.

Referring to the accompanying drawing, A represents the upper part ofthe body of the heat er; B, the fire-pot or chamber; C, the grate;

and D, the ash-pit. E E is the fuel-reservoir. F is the main escape-pipeor iiue for the products of combustion. This pipe is connected in adirect manner, as by a branch, b, under control of a damper, c, with thebody A of the heater, to provide for a direct draught on starting there, and at other times when required. Said pipe F is also connected withthe base G, which forms a flue round the ash-pit, and is incommunication above, as hereinafter described, with other uptakes usedin the regular or indirect draught.

To circulate the products of combustion for the heating of the air,either to warm the apartment in which the heater is placed, or todistribute it by suitable ducts to other apartments, the products ofcombustion, on turning the damper c, are made to lirst pass intoupper-side pipes H forward of partitions d, and then to descend downdippipes l to the base G, through which they pass to up-take pipes J andto the main escapepipe F, the up-takes J connecting at their upper endsback of the partitions d with rear extensions ofthe side pipes H. Thisarrangement of pipes obtains a most effective and economicalheating-surface without iinpairing the draught.

The air to be heated is introduced by holes e, in the bottom plate ofthe base G, to air-heating chambers L, and, after being warmed, passedout through corresponding holes f in the top of the base, forcirculation among and around the pipes H I J, and other exteriorradiating surfaces ofthe heater. These air-heating chambers L aresituated within the base G, and so arranged as to be exposed on theirsides in a direct manner to the heat of the base-flue, and to radiationfrom the ash-pit of the heater. This double eX- posure effects aconsiderable warming of the air before its passage to or around theexterior radiating surfaces of the heater.

The front plate K of the hea-ter is hung and secured to its place bypassing it obliquely in a backward Adirection at its bottom behind thelugs or projections g on the bottom plate of the base, and then swingingor passing its upper end over the top of the heater, where it is securedby a screw-bolt and nut, l1, to a projection from the top of the heater.This mode of introducing1 and attaching the front pla-te of the heateradmits ot' its ready insertion behind the center ornament of themantle-piece without damaging or disturbthe latter.

The fuel-reservoir is made in two horizontal parts or sections, E E',the lower one E of which is made in the form of a detachable curtainthat is attached to the other section E by bayonet or other suitablefastenings, 1', so that said lower section, when damaged by the actionof the tire, can readily be replaced by another like portion by simplyturning it so as to unhook it from the upper section E, and removing itthrough the doors k of the heater, said doors being so ar Fcured byLetters Patent, is-

The combination of the side pipes H, dip-pipes I, 11p-takes J,air-heating chamber L, flue G, and escape-pipe F, all arranged withrelation to the body A and lire-chamber B for operation, as shown anddescribed.
